To aZZ 'whom imag concern.'

Be it known that l, GEORGE SIMoon, u

.citizen of the United States, and a resident of Trenton, in the county ofMereer and Stute of New Jersey, have inventedA e new und Improved Tubular Insulator, of which the *following is aKfull, clear, and exa-ct description. v

This invention relates to insulators or circuit breakers and has particular reference to devices of this character employed for the purpose of supporting electrical cony Wires, or in other capacities sion of electric currents.

Among the objects of the invention lis to construct an insulator of the character referred to which may be easily and cheaply manufactured by the use of :my suitable nierchines and which devices will not only be structurally strong, but will be of superior design with respect to electrical conditions.

Theforegoing and other objects of this invention will hereinafter be more fully described und claimed and illustrate-d in the druvvings accompanying` this specification in which like characters of reference indicate corresponding parts in allthe views, and in which- Figure 1 is n vertical section of one type or design of my improyed insulator; Fig. 2 is a, simiiar view of the same, taken at right ongles to Fig. l; 1nd Figs. 3 and 4 are `views corresponding to Figs. 1 and 2 respectively of another forni Referring particularly tothe drawings I Y show at 10 the main portion of my'insuletor which is made preferably in o r'by a stenderd tube machine, uslng plastic clay es the material. I prefer this material esrieciellyy for high tension service, although for certain purposes as, for instance, in low voltage, dust may be used.

As shown in Figs. 1 und 2, the insulator 10 is provided with a pair of holesll and 12 extending longitudinally therethrough parallel to each other, said holes being connected by etransverse channel 13 at one end of' the insulator. The bottom of thischan- EPotented Sept. Q, 1913.

Serial No. 7533,'78.

nel 13 is preferabiy bounded so as to pro vide en easy curvature for en attaching device in the form of cable or Wire 11i extending Athrough the holes 11 and 12. 1 also provide n, transverse hole 15 extending through the insulator at substantially "the center thereof eind et 'the center oi curve.- ture of said. channel bottom. Thisv transf verse hole is for-the purpose of another ettuchment indicated at 16. At 17 l provide lateral extensions or skirts preferably on' both sides of the insulator edjecentthe one end thereoig which may be mede integral with the insulator or seperate therefrom und suitably connected thereto.y The 'insulator as shown in these iigures being substantially flat,- the skirts 17 provide suliicient spacing of the attachment 16 from the uttaohment 14. The cable 16 muy be seat-cd in notches 17"to assist in maintaining they ports in proper relation to one another.

In Figs. 3 and 4t the insulator body 10 is of e slightly different Yiorin from that shown in Figs. i und Q3 'but is provided with correspendingl longitudinal parallel l holes 11 and 12v connected by n. transverse depression or sent 13". l? also provide e single transverse Ahole 15" having similar characteristics to those described inv connection with the irst form of the invention.

As indicated in Fig., one end of Ythe insulator vis `tiered outwardly et 17' corrosponding to the skirts 17 above described. As u ineens to increase the surface :treu of these insulator bodies they may be forined With corrugotions 18 end either end. be provided with e circumferential groove 1f; for the sume purpose. These.corrugutions ond grooves aviso assist in excluding .ice und dirt.

HavinnA thus described my invention, l claim es new und desire to secure by Letters Pntent1- ln e device of the .character set forth, en, insulator body' of tubular formation hovng s ptir of holes extending therethrough longitudinnily end having un opening nl ranged et e right ongle to theuforesuid holes, and connectors disposed respectively in said holes and said openingand extendname to this speoica-tion in the presence ofA ing from the body in opposite dreot0us,-Said two subscribing witnesses. body bein@ formed adjacent one end with a -1 Y y plurality tdf collugations and at the other GEORGE] bIML/on' end with a circumferential groove 24, sublVitnesses: stnvntially as set forth.

In testimony whereof I have signed my J. CQNNER FRENCH.
